Title: Paper feed device capable of detecting presence of recording paper
Inventor: IKEDA MASAAKI
IPC: G03G15/00
Filed: 1986-03-11
Abstract: PURPOSE:To aim at enhancing the efficiency of copying operation, by providing a detecting means composed of two sensors and an actuator to carry out the detection of presence of a recording sheet manually inserted and the detection of presence of a recording sheet from a cassette. CONSTITUTION:An actuator 21 is composed of two detecting sections 22, 23 and a pair of light shielding plates 24, 25 which are integrally incorporated, and is rotated about a rotary shaft 21a as a rotational center in association with the operation of the detecting section 22 or 23 for detecting a recording sheet. With this arrangement, a shield plate 24 or 25 allows a light beam from a photosensor 32 for detecting a sheet fed from a cassette or from a photosensor 33 for detecting sheet manually inserted to pass or to be shielded. As a result, a recording sheet is surely fed without the supply and replenishment being neglected, thereby it is possible to enhance the efficiency of copying operation.

Title: Semiconductor memory
Inventor: INOUE TAKESHI
IPC: G11C7/00
Filed: 1997-03-07
Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor memory that can effectively relieve a defective bit of a memory cell array without sacrificing the access time in a high speed read-out mode such as a page mode and the like. SOLUTION: Redundant circuits, RDN0-RDN3 are provided for each word data constituting one page. And, each data DOS0-DOS3 constituting one page read out from a memory array is replaced by replacement data RDAT0-RDAT3 from redundant circuits RDN0-RDN3 in accordance with existence of defect, after data of one page is restructured, it is time-divided and continuously outputted. Therefore, since a defective bit is replaced making a page as a unit in a step, at which the first word of a page in which defect exists is accessed, defect is already relieved when read-out after the second word is performed, page access can be performed at a high speed.

Title: Position detecting method
Inventor: UEMA TAKEARI
IPC: G01B7/00
Filed: 1978-05-08
Abstract: PURPOSE: To reduce the time required for detection by so constituting positions marks that the coordinates X, Y of alignment marks mutually associate and obtaining the coordinates of positions only through scanning of the coordinates in one direction of X or Y.  
     CONSTITUTION: Alignment marks 12a... 12d of isosceles triangle are used for a substrate 11. If the two intersection points of an isosceles triangle 12 and a beam scanning line 13 are let to be α 1 , α 2  respectively (XB denotes the x coordinate of the beam scanning lines), the coordinates X, Y are given by formulas [1], [2]. As are evident from these formulas, the coordinate X is measured with errors half those of the coordinate Y as against measurement errors of α 2 , α 1 . Hence, as the inclination of the two sides of the triangle is made steeper, the values of the coordinate X of better accuracy are obtained. Since the two coordinates of X, Y are  obtained simply through scanning in one direction, the position detecting time may be reduced to 1/2 that of ordinary ones.

Glass balls 1 as standard particles are sprayed atop this recording medium and are thereby brought into contact therewith. The recording medium is put into a thermostatic and hygrostatic chamber of a clean type in this state and the environment is maintained at and under a prescribed temp. and humidity. Condensed water 6 of a liquid phase state is then generated in the microspacing between the ball 1 and the recording medium from the steam 5 in the atm. air by a capillary condensation effect. A corrosion ring 7 of an annular oxidized part is generated when the recording medium is stored in this state for a specified period of time in the thermostatic and hygrostatic chamber. The quantitative corrosion environment is attained by the progression of the corrosion of this ring 7 and the corrosion of the recording medium is decided at a certain point of the time when the annular trace of corrosion grows.

IPC: C22C33/02
Filed: 1994-02-28
Abstract: PURPOSE:To increase the performance of the characteristics of an oxide dispersion strengthened alloy by subjecting NiO-MgO solid solution or FeO-MgO solid solution as full ratio solid solution to selective reducing treatment by a reducing gas and uniformly dispersing the fine grains of MgO into a mother phase of Ni or Fe metal. CONSTITUTION:Powdery NiO and powdery Mg (OH)2 are mixed, and after that, Mg (OH)2 is thermally decomposed to form into MgO. Next, it is subjected to compression molding to allow NiO and MgO to enter into solid solution. After that, this solid solution is subjected to reducing treatment by using a reducing gas, preferably, gaseous CO and, more preferably, gaseous H2, and NiO is subjected to selective reduction. At this time, MgO is formed into fine crystals, which are uniformly precipitated into the Ni mother phase. Moreover, since pores are generally present in the sintered body in this stage, densifying treatment is furthermore executed by compressing treatment, heat treatment or the like. Even in the case FeO is used, treatment is executed by the method similar to the case in NiO.

Abstract: PURPOSE: To increase the degree of freedom for control of the characteristics by removing temporarily the insulating thin film used for the ion injection, giving annealing with covering of the insulating thick film to prevent the effect of contamination on the surface of the insulating film, and then securing the control of the characteristics of MOSFET according to the ion injection terms to the offset channel.  
     CONSTITUTION: Resist mask 11 is provided on surface oxide thin film 10 after formation of n-layer 3 and 4 on p-type substrate 1, and then n-type ion is injected to control the surface potential of offset channel 9. Mask 11 plus all of oxide film 2 and 10 are removed, and oxide film 12 is formed newly. After this, the annealing is given to activate the injected ion. Thus, a high annealing temperature can be applied since the electrode is not formed yet, and thus the thcikness of film 12 can be increased so that the surface contamination of film 12 may not effect the surface potential of channel 9. Then the opening is drilled selectively to film 12 to form gate insulating film 5, and then the opening is drilled selectively to film 5 to form electrodes 6∼8. With this method, the ion injection amount can be increased up to 10 15 cm -2 , thus increasing the degree of freedom for the characteristics.
